TANK-HEATER.

Patented Dec. 1, 1914..

Application filed February 7, 1914. Serial No. 817,335.

To all whom it may concernn Be it known that I, HERMAN A. SCHUCK, acitizen of the United States, residing at Parkersburg, in the county of Butler and State of Iowa, have invented certain new and useful Improvements in Tank-Heaters, of which the following is aspecification, reference being had to the accompanying drawings. i

This invention relates to new and useful improvements in heaters and more particularly to tank heaters, the main object of the invention being to provide a heater of the above character which is preferably adapted to be used in heating stock watering tanks during the cold periods of the year, and is so constructed and arranged that a maxi-.

mum amount of heat may beobtained by the use of a minimum amount of fuel.

Another object of the invention is the pro: vision of a tank heater of the above character. which possesses advantages in points of efficiency and durability, is inexpensive to. manufacture, and at the same time is simple in construction and operation.

With the above and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of theparts that I shall hereinafter more fully describe and claim.

For a full understanding of the invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 is a longitudinal sectional view, illustrating the invention. Fig. 2 is a detail perspective view of the heater. Fig. 3 is a longitudinal sectional view illustrating a modified form of the invention. Fig. l is a detail perspective view of the same.

In carrying out my invention, instead of mounting the body of the heater 3 directly within the cement which forms the tank, I provide a corrugated ring, as shown at 15, which is adapted to be arranged within the opening 2 and spaced from the outer end of the heater 3. The inner edge of this ring 15 is provided with an inturned flange 16 which extends inwardly and engages around the heater 3' the entire circumference thereof. The grate 6' is constructed with the down-turned flanges 7 which are riveted or otherwise secured to the interior of the body of the heater. The body. of the heater is also divided in its two chambers 8 and 9' which compose the ash pit and the-heating chamber or fire box; In this form of the invention, I prefer to arrange thesmoke stack 5 adjacent the outer. end of the heater 3 and disposed within the walls of the tank 1.

Arranged within the chamber 8 and extending from theforward end of the receptacle to a point adjacent the rear end thereof is a plate 17 which, provides a suitable channel 18 whereby the smoke gases and heat from the fire within the chamber 8 is directed toward the forward end of the device, thence passing upwardly through the stack 1 5. From this it will be apparent that by having the fire disposed within the box 8' and in order toreach the outletstack 5,-the heat and smoke must travel inwardly toward the inner end of thetank, thence upwardly and back toward the forward end ofthe tank, until itreaches the stack 5, the same then passing up the stack and out into the atmosphere. It will be apparent that by havingthe heat and smoke circulating in this manner, the water contained within the tank will be heated more readily than if the usual means for circulating were provided. a i 1 .InFig. 4 I have illustrated a detail perspective view of the invention which shows the same construction as just described in regard to F ig..3. In this figure, the lower door 10 which communicates with the ash pit 9 is hingedly mounted upon the end of the heater, the same as illustrated in Fig. 1, and is adapted to close communication between the ashpit and the exterior of the tank. The heating chamber 8 is also open at its outerend and provided with a swinging door 12 which is hinged to the body and is adapted to close the same when desired. It will be apparent that by having the ring 15 arranged between the tank and the cement the heat from the tank will prevent the cement from cracking, as is generally the cause of the destruction of the water tanks which are now in use and are formed of concrete.

It will be seen that the device herein shown'and described is more simple in con struction and has a more thorough circulation of heat than the tank heaters in use at the present time. In the present construction, the heat is forced to travel to the inner end of the heater, thence back to a point adjacent the other end thereof and then out the stack 5.

In Fig. '3 I have illustrated a modified form of the invention wherein the smoke stack 5 is located upon the outside of the tank instead of on the inside, as shown and described in the first forms.

As illustrated in the drawings, the plate 17 extends out beyond the outer end of the heater as does also a portion oftheiheater itself, so as to extend the chamber 18 The lower end of'the smoke stack 5 is arranged within theouter end of the chamber 18 and securely retained in position by having its lower end bent outwardly to provide a flange 19 which is adapted to engage with the upper portion of the heater 3 so as to prevent the stack from pulling away from the chamber. From the above, it will be apparent that in this form of the invention, the smoke and superfluous heat is carried outside of the tank before passing upwardly into the atmosphere. The outer end of the chamber 18 isopen and the opening therein is normally closed by means of the-swinging door 20.

From the above description takenin con-' nectlon with the accompanymgdrawmgs,1t

will be readily apparent that I haveprovided a simple, and durable'tank heater which is preferably adapted for use in heating stock watering tanks and it will be noted that by having the heater itself within the liquid contained in the tank, the contents will be more readily heated than if the heater were arranged beneath the tank. It will be-apparent that in view of thefact that the tank is constructed of concrete, the heater itself must be arranged within the tank. In order to prevent the heat from cracking the concrete,-the ring 15 is arranged around the outer end of the heater and disposed between the same and the concrete forming the tank. It will be apparent,

however, that while I have shown my improved heater used in connection with a tank-of concrete construction, the same may be used with any form of tank. It will also be apparent that my improved "heater is extremely simple in construction and can be [Copies of 'thhpatent may be obtained for five cents each, by'addressiiig the manufactured and'placed on sale the market at comparatively smallcost.

While I have-shown and described "the form .of my invention, it will be obvious that various changes in the details of construction and proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the PP Hded claims. i i.

What I claim, is: g

'1'. The combination with a composite tank having an opening in one-end thereof, of a heater arranged within the tank and having its'outer end projected through the opening in spaced relation therewith, a. corrugated protecting ring arranged within the open-,

mg and surrounding the outer end of the heater, and an annular flangeformed on the inner edge 'of the ring and adapted toproject inwardly and engaged .withthe outer periphery of the bodyof the heater, as and for the purpose set forth.

2. Thecombination with a composite tank having an opening in one end'thereof, .of a heater arranged therein, a'corrugated ring arranged within the opening'in spaced rela-.

tion with -the end of the heater, an annular flange formed on the inner edge of the ring the heater, whereby to. provide indirectcon1-- munication between the smoke stack and the body of the heater, as and for the purpose set forth. j l I In testimony whereof I hereunto afi'ix my signature in the presence of two witnesses.
